Maps were created in ArcGIS 10.5 (ESRI; Redlands, CA, USA). Individual species distributions generally followed the same pattern (Figure 9); however, some species were more widely distributed than others, such as B. orientalis, B. gargarizans, D. japonicus, G. emeljanovi, P. nigro...
Automation of visible land boundary detection can be used to revise existing cadastral maps and to automatically identify areas where updates are needed. At this point, it should be emphasised that not all cadastral boundaries are visible and that some of them are difficult to detect on UAV ...
forestland characteristics; non-point source pollution; SWAT model; forest optimization configuration1. Introduction Nonpoint source (NPS) pollution is a major environmental problem that seriously affects residents’ living conditions and economic development because it is nonspecific and difficult to identify...
Considering that the aim of this study was the reconstruction of urban systems, the analysis of individual cities in the historical period, as well as the point pattern of cities, needs to be strengthened. In this study, more common spatial analysis methods such as the spatial Lorenz curve, ...
The point cloud is a direct product of drone-based remote sensing. The point cloud not only contains the spectral information of land cover but also the volumetric information of land surface; therefore, a classification method, which is based on the slope of the initial terrain model, was use...
On the basis of the original data collection, ArcGIS 10.8 (Esri, Redlands, CA, USA) software was used to establish the thematic layers of each evaluation index, the unified transformation and projection of the coordinate system were carried out, and the coordinates adopted the unified WGS 1984 ...
[43]. Therefore, the reliability of OBIA is determined by appropriate image segmentation, and classification accuracy may vary depending on these results. Here, ArcGIS Prov.2.8 developed by ESRI (Redlands, CA, USA) was used for image segmentation and the image with nine orthoimages stacked was ...
Figure 2 shows the hanging line L1 in linear correlation with the 3D parcel boundary line, and the hanging point P1 linearly related to the 2D land boundary line and the hanging line L2, independent of the above-mentioned parcel linearity. Figure 2. Schematic diagram for topology classification...
Each point is associated with a horizontal angle 𝜙ϕ and vertical angle 𝜃θ. These coordinates are automatically converted into (𝑥,𝑦,𝑧x,y,z) coordinates relative to the TLS. The laser scans the area every hour in low resolution, which corresponds to 0.030.03° angular point ...
